PC- P3 500, 256 megs, BX board Abit BH6

Quake II used as benchmark since we know it muli-textures, clean install with 3.20 patch. 640 x 480 and 800 x 600 used 3dfx Q2 driver, 1024 used opengl driver as Q2 would not run at 1024 with native 3dfx Q2 driver.

No minidriver used, test run 3 times to make sure fps were stable. Last 3dfx Voodoo3 drivers used on all cards. Turok does not display correct with 8 meg Voodoo3 cards for some reason, hence no numbers for the 8 meg cards.

V3-2000 AGP, 16 megs at 143 mhz

Q2 640 = 115 fps
Q2 800 = 102 fps
Q2 1024 = 72 fps

Turok = 166 fps

V3-1000 Gateway Bonesteel, 8 megs, 143 mhz, 1 TMU
(bios states V3-1000 2.15.06-SG on boot up)

With one TMU

Q2 640 = 95 fps
Q2 800 = 66 fps
Q2 1024 = 43 fps

Interesting that the default on the Bonsteel card is one TMU! With second turned on in registry the following results-

Q2 640 = 115 fps
Q2 800 = 103 fps
Q2 1024 = 73 fps

So the Bonesteel is the same as a Velocity 100 due to the 8 megs of SGRAM and one TMU turned off by default. Not a good way to make a first impression!

Velocity 100, 8 megs, 143 mhz, 1 TMU
(bios states Velocity 100 on boot up)

Q2 640 = 95 fps
Q2 800 =  66 fps
Q2 1024 =  43 fps

Compaq V3-1000, *16 megs*, 125 mhz, 2 TMU's
(no bios display on start up)

Q2 640 = 114 fps
Q2 800 =  95 fps
Q2 1024 = 64 fps

Turok = 150 fps

The Compaq card clearly has 2 TMU's enabled out of the box.

Conclusion- Turok doesn't like 8 meg V3 cards, Turok doesn't strain the V3 cards very much with a 500 mhz cpu (hence the small spread between 125 and 143 mhz) Q2 makes use of 2 TMU's if present.

The V3-1000 seems to be a V3 with or without the second TMU turned on, with either 8 or 16 megs depending on whose computer it is installed in. The Compaq version has 2 TMU's, 16 megs and 125 mhz clock, the Gateway version has 1 TMU enabled, 8 megs and 143 mhz clock.

And of course the second TMU can be turned on via the registry on the "one" TMU cards.

The V3-1000 would use also a chip written 355-0025-01 on it.
Would be in fact a "castrated" Voodoo 3.

The Velocity would be based on a 3dfx 500 chip (500-0017-05).


I'm not sure the chip numbers are a reliable indicator, I have four V3 cards here with no heatsinks and all have different numbers.

You know I was thinking about the Bonesteel cards this morning.. There is no real reason for 3dfx to shutoff the second TMU in this OEM product... So I was thinking that perhaps they had enough chips with a defective TMU to make it profitable to recycle as the Velocity or Bonesteel cards.

It's well known that ATI and Nvidia do the same thing, thoughts?

The V3-1000 Compaq and the V3-1000 Gateway are different cards.
